Description
본 고안은 세탁기에 관한 것으로서, 더욱 상세하게는 세탁기의 표시부기판과 기능부기판이 각각 고정되는 양 고정부재의 접촉면 사이에 갭(Gap)을 형성하여 코팅액 등의 이물질이 접촉면 사이로 개입되더라도 고정부재가 휘어지는 등의 변형을 방지하여 동작상의 신뢰성을 향상시킬 수 있는 세탁기용 회로기판의 휨 방지구조에 관한 것이다.The present invention relates to a washing machine, and more particularly, a gap (Gap) is formed between the contact surfaces of both fixing members to which the display unit substrate and the functional unit substrate of the washing machine are fixed, so that the fixing member is bent even if foreign matter such as coating liquid is interposed between the contact surfaces. The present invention relates to a warp prevention structure of a circuit board for a washing machine that can prevent deformation of the back and improve operational reliability.
일반적으로 세탁기는 세탁물의 종류에 따라 세탁-헹굼-배수-탈수행정을 수회 반복하면서 자동 또는 수동으로 세탁을 행하는 기기로서, 도 1은 이와 같은 세탁기를 도시한 사시도이다.In general, a washing machine is a device that performs washing automatically or manually while repeating washing-rinsing-drainage-dehydration stroke several times according to the type of laundry, and FIG. 1 is a perspective view of such a washing machine.
즉, 세탁기는 크게 물이 공급되는 급수수단(1)과, 상기 급수수단으로부터 공급받은 물의 수류에 의해 세탁이 행해지는 몸체(2)와, 세탁을 마친 오염수를 배출하는 배수수단(3)으로 구성되어 있다.That is, the washing machine includes a water supply means 1 to which water is largely supplied, a body 2 to be washed by the water flow of water supplied from the water supply means, and a drain means 3 to discharge the contaminated water after washing. Consists of.
한편, 상기 몸체(2)의 상부면 일측에는 세탁기의 동작의 설정 또는 동작을 제어하는 컨트롤러(4)가 설치되어 있으며, 이 컨트롤러는 각 기능의 조작버튼을 누름에 따른 전기적 신호를 마이컴(도시는 생략함)이 감지하여 동작을 제어하게 된다.On the other hand, one side of the upper surface of the body (2) is provided with a controller (4) for controlling the setting or operation of the operation of the washing machine, the controller micom the electrical signal according to pressing the operation button of each function ( Omit) to control the operation.
특히 도 2와 도 3에서와 같이 컨트롤러(4)는 몸체(2)에 결합되는 외부판넬(41)과, 상기 외부판넬의 하부에 밀착 설치되는 제 2 고정판(7)에 의해 체결고정되고 세탁기의 동작을 제어하는 기능부기판(8)으로 구성되어 있다.In particular, as shown in FIGS. 2 and 3, the controller 4 is fastened and fastened by an outer panel 41 coupled to the body 2, and a second fixing plate 7 installed close to the bottom of the outer panel. It consists of the functional part board | substrate 8 which controls an operation | movement.
즉, 상기 제1고정판(5)의 전면에는 삽입공(9)이 형성된 탄성체의 고정편(10)이 복수개 형성되어 있고, 상기 제2 고정판(7)의 전면에는 상기 제 1 고정판(5)의 삽입공(9)에 삽입되는 걸림턱(71)이 각각 형성되어 있다.That is, a plurality of fixing pieces 10 of an elastic body having insertion holes 9 are formed on the front surface of the first fixing plate 5, and the first fixing plate 5 is formed on the front surface of the second fixing plate 7. Locking jaws 71 are inserted into the insertion hole 9, respectively.
따라서 제 1 고정판(5)의 삽입공(9)으로 제 2 고정판(7)의 걸림턱(71)을 끼우고 절연 및 세탁수의 유입을 저지하도록 액상의 코팅액으로 표면처리하여 밀봉하게 된다.Accordingly, the locking jaw 71 of the second fixing plate 7 is inserted into the insertion hole 9 of the first fixing plate 5, and the sealing is performed by surface treatment with a liquid coating solution so as to prevent insulation and inflow of wash water.
상기와 같은 컨트롤러(4)의 코팅작업시 밀착고정된 제 1, 2 고정판(5)(7)사이로 액상의 코팅액이 흘러들어가게 되면 후에 이 코팅액이 응고되어 고체상태가 되면 일정형태의 부피를 형성하여 상기 제 1, 2 고정판(5)(7)사이를 벌어지게 하는데, 이때 코팅액이 일정치 않게 유입됨에 따라 응고시 제 1, 2 고정판과 이에 체결된 표시부기판(6)과 기능부기판(8)에 휨에 발생하게 된다.When the coating liquid flows into the first and second fixing plates 5 and 7 fixedly adhered to each other during the coating operation of the controller 4, the coating liquid is solidified to form a volume of a certain shape. The first and second fixing plates 5 and 7 are separated from each other, wherein the first and second fixing plates, the display part substrate 6 and the functional part substrate 8 fastened to the first and second fixing plates when the coating solution flows inconsistently. Will be caused by bending.
이는 각 기판의 기능에 영향을 주게되어 부분적인 기능의 상실로 동작불량이나 고장의 원인이 되었으므로 기기의 신뢰도를 저하시키는 문제점이 있었다.This affects the function of each board, which causes a malfunction or failure due to partial loss of function, thereby lowering the reliability of the device.
본 고안은 위와 같은 종래의 문제점을 감안하여 안출한 것으로서, 표시부기판이 고정되는 제 1 고정판과, 기능부기판이 고정되는 제 2 고정판의 사이에 갭이 형성되도록 제 1 고정판의 저면과 제 2 고정판의 상면중 어느 하나에 돌출부를 형성함으로써, 코팅작업시 제 1 고정판과 제 2 고정판 사이로 코팅액이 흘러들어가 응고되더라도 갭으로 인해 각 고정판 및 기판의 변형을 방지할 수 있는 세탁기용 회로기판의 휨 방지구조를 제공하는 것이다.The present invention is conceived in view of the above-described conventional problems, the bottom of the first fixing plate and the second fixing plate so that a gap is formed between the first fixing plate to which the display unit substrate is fixed, and the second fixing plate to which the functional unit substrate is fixed. By forming a protrusion on one of the upper surfaces, even if the coating liquid flows between the first fixing plate and the second fixing plate during the coating operation, the bending prevention structure of the circuit board for the washing machine can prevent deformation of each fixing plate and the substrate due to the gap. To provide.

첨부도면 도 4 및 도 5를 참조하여 설명하면 다음과 같다.The accompanying drawings will be described with reference to FIGS. 4 and 5 as follows.
즉, 세탁기 몸체(2)의 상부면 일측에는 세탁기의 동작을 설정, 제어하는 컨트롤러(4)가 설치되어 있는데, 이 콘트롤러는 상기 몸체(2)에 결합되는 외부판넬(41)의 하부에 기능선택 및 동작상태 등을 표시해 주는 표시부기판(6)과, 상부 표시부기판이 체결되고 전면에 삽입공(9)이 천공된 고정편(10)이 복수개 구비된 제 1 고정판(50)과, 상기 제 1 고정판의 하부에 밀착 설치되고 전면에 상기 제 1 고정판(50)의 삽입공(9)에 삽입되는 걸림턱(71)에 각각 형성된 제2고정판(7)과, 상기 제 2 고정판에 체결되어 세탁기의 동작을 제어하는 기능부기판(8)으로 구성된다.That is, a controller 4 for setting and controlling the operation of the washing machine is installed at one side of the upper surface of the washing machine body 2, which controller selects a function at the bottom of the outer panel 41 coupled to the body 2. And a first fixing plate 50 having a plurality of display pieces 6 for displaying an operation state, a plurality of fixing pieces 10 on which an upper display part substrate is fastened, and an insertion hole 9 is drilled on the front surface thereof. The second fixing plate 7 which is installed in close contact with the lower part of the fixing plate and formed in the locking jaw 71 which is inserted into the insertion hole 9 of the first fixing plate 50 on the front surface thereof, and is fastened to the second fixing plate, It consists of a functional substrate 8 for controlling the operation.
특히, 상기 제 1 고정판(50)의 저면에는 일정한 돌출높이를 가진 돌출부(51)가 형성되어 있는데, 이 돌출부는 다수개의 돌기(51a)를 형성되어 제 2 고정판(7)과의 밀착 결합시 접촉면 사이에 돌기(51a)높이 만큼의 갭(Gap)(H)을 형성토록 한 것과, 도 6에서와 같이 상기 제 1 고정판(50)에 형성된 돌기(51a) 대신에 동일한 높이로 가로 세로 방향으로 연속되는 리브(51b)를 형성하면, 이 리브의 높이만큼 제 1, 2 고정판(50)(7)사이에 갭(H)을 형성하는 본래의 효과와, 제 1 고정판(50)의 강도를 보강하는 부수적인 효과도 얻을 수 있다.In particular, the bottom surface of the first fixing plate 50 is formed with a protrusion 51 having a predetermined protrusion height, which is formed with a plurality of protrusions (51a) the contact surface when in close contact with the second fixing plate (7) The gaps (H) as much as the height of the projections 51a are formed therebetween, and as shown in FIG. 6, continuous in the horizontal and vertical directions at the same height instead of the projections 51a formed on the first fixing plate 50. When the rib 51b is formed, the original effect of forming the gap H between the first and second fixing plates 50 and 7 by the height of the rib and the strength of the first fixing plate 50 are reinforced. Side effects can also be obtained.
또한 상기 돌기(51a) 또는 리브(51b)를 제 2 고정판(7)에 형성해도 무방하며, 이때도 상기 제 1 고정판(50)에 형성했을 때와 동일한 효과를 얻을 수 있다(도 7 참조).In addition, the projection 51a or the rib 51b may be formed on the second fixing plate 7, and at this time, the same effect as when formed on the first fixing plate 50 can be obtained (see FIG. 7).
제 1, 2 고정판의 접촉면 사이에 갭을 형성함으로써 절연을 위한 코팅작업시 코팅액이 접촉면 사이로 유입되어 응고되더라도 갭으로 인해 제 1, 2 고정판에 영향을 미치지 않으므로 휨을 방지할 수 있으며, 리브를 형성하면 고정판의 강도를 강화하는 효과도 얻을 수 있다.By forming a gap between the contact surfaces of the first and second fixing plates, even if the coating liquid flows between the contact surfaces and solidifies during the coating operation for insulation, the gap does not affect the first and second fixing plates, thereby preventing warpage. The effect of strengthening the strength of the fixed plate can also be obtained.
